FLASHING.

Specification of Letters Patent.

. Application filed May 16, 1912. Serial No. 697,647.

To all whom t may concern:

Be it known that LEWING M. FORBES, a

citizen of the United States, residing at- Chica-go, in the county of Cook and State of illinois, h ave invented certain new and useful Improvements in Flashings,.of which the following is a specification.

My invention relates in general to the construction of roofs and more particularly to in'lprovements in roof flashings.

Considerable difficult-y is experienced in so connecting roofs with adjacent upwardly projecting walls, chimneys, sky-lig ts, etc., as to secure a permanent water-proof union. This has proved particularly difficult in the case of roofs composed of felt or similar flexible fabrics.

The primary object of my invention is to provide an improved flashing by means of which a waterproof connection may be made between a roof and adjacent wall in a convenient and efficient manner.

A further object of my invention is to provide a roof flashing which will be simple in construction, inexpensive in manufacture, and durable in use.

My invention will be more fully disclosed hereinafter with reference to the accompanying drawings, in which the same is illustrated as embodied in a convenient and practical form, and in which- Figure 1 is an eleva-tional view showing my improved flashing in position, the roof bein`g'shown in section; Fig. 2 a View similar to Fig. 1 showing my fiashing applied to a different form of roof; Fig. 3 an enlarged vertical section through my improved Hashing, the adjacent portions of the roof and 'wall being shown; Fig. 4 an elevational view looking toward the left in Fig. 3; Fig. 5 an elevational view showing the flashing arranged for use in two different horizontal planes; Fig. 6 an enlarged sectional view of a joint between adjacent sections of the flashing. Fig. 7 a plan view of the clamp and a portion of its sup orting bracket; Fig. 8 a sectional view on line -8, 8, Fi 7 and Fig. 9 a plan view of the' end o the bracket which supports the clamp.

Similar reference characters are used to designate similar parts in the several figures of the drawings.

Reference letter A, referring articularly to Fig. 1, designates a brick wall) projecting above' the roof support B.

C indicates the roofing material, such for instance as felt or similar roofing fabric.

D designates the outer apron of my improved flashing which overlies the up er edge of the upturned portion of the roofihg material C.

E, E designate clamps spaced predetermined distances apart which serve to force the flexible apron of the flashing inward] against the underlying portion of the roo ing material.

In Fig. 2 A. designates the wall which projects above the able roof B', while C designates the roo ng material which extends upwardly adjacent the wall and underlies the pliable apron D of the flashing. The clamps E are located at different levels so as to securely retain the apron of the flashing in close contact with the underlying roofing material.

The details of the construction of my improved flashing are more clearly shown in Figs. 3 and 4. F designates the backing of flashing which may be formed of any suitable material, preferably stiff, such as galvanized sheet iron. The backing F is formed of a horizontal portion f adapted to be insertedbctween adjacent horizontal rows of bricks, and a depending vertical portion adapted to overlie the lower rows of bricks. The horizontal portion of the backing is preferably folded upon itself so as to receive betweeny the members thereof the upper horizontal portion of the pliable aplm, which is preferably formed of sheet lea The horizontal portion of the backing F is secured to a bracket G by any suitable means, such for instance as rivets f, one of which may also pass through the inclosed portion of the apron and thereby secure thel same to the backing and to the bracket. The front end of the bracket is provided with a depending portion G through which extends a clamp screw H, which engages the clamping member E and forces the same against the pliable apron D, thereby clamping the roofing material C between the same and the backing F.

Any suitable means may be provided for pivotally supportin the up er end of the clamp upon the racket such for instance as shown in detail in Figs. 7, 8 and 9, in which a T-shaped opening is formed in the end of the bracket G through which Patented Jan. 28, 1913.

detachably extends a projection on the upper end of the clamp. The head or projection ev is of a length to pass through the widest portion g in the slot of the bracket, while the neck e, which connects the head e with the clamp E, is of a width to passl within the restricted portion g of the slot so that the head will overlie the side edges of the ortion g gf the slot and thereby support t e clamp upon the bracket. Al plurality of such clamps are provided spaced 'sufficiently 'close together to insure the proper engagement of the flashingv with the roofing material.

A triangular ller strip of wood K is preferably located inthe angle between the` the dashing occupying different horizontal.

planes, and hence a portion thereof will be inserted between two horizontal rows of bricks, while an adjacent portion will be inserted between two other horizontal rows of bricks at a lower or higher level, according to the inclination ofthe roof. In Fig. 5 F indicates the backing to which is secured the pliable apron D to be inserted at one plane and from which depends a vertical portion F of the backing to ywhich is secured va vertical portion D of the apron. From the lower endr of the vertical portion F of the backing there extends a horizontal portion F2 to whichis secured a horizontal portion D2 of the apron. In order to insure water-tight joints between the horizontal .and vertical portions of the flashing overlapping ears are formed on the connected sections of the apron such as d, d', d2, which are secured within the folded portions of the sections of the flashing by rivet-s.

The manner of using my improved flashing will he readily understood from the foregoing description.

A section of the flashing is placed along a row of bricks above the roof support and a superimposed row of bricks is then placed uponA the horizontal portion of the dashing, as willbe evident from Figs. 3 and 4. The brackets G are in a similar manner supported between adjacent rows of brick in the wall projecting above the roof. Wheny the roofing material C is laid on the roof support B, the edge thereof adjacent the wall is inserted between the backing F and liable apron D of the dashing. The clamps are then engaged with the respective tight joint between the roof and upwardly projecting walls ofl all characters, and Vthat the-union between the roofing materiab and upwardly projecting walls affected by the use vof my improved ashing will be permanent in character owing to the -absence of sharp bends in the roofing material and to the absence of any tearing or perforation of the roofing material in securing flashing thereto.

I claim: e

1. A roof iashing comprising a backing, and a pliable apron between which and the backing the rooting material is adapted to be inserted.

2. A roof ashing comprising a backing, and a lead apron between which and the backing the rooting material is adapted to be inserted. l

3. A roof iashing comprising a stiff backing, and a pliable apron secured adjacent the upper edge of said backing, the roofing material being adapted to be inserted between the backing and apron.

49A roof flashing comprising a horizontal portion adapted to be inserted between adjacent rows of bricks, and a depending vertical portion,'said flashing being composed of a sti backing and a pliable apron secured to ythe backing adjacent its upper edge and between which and the backing the roofing material is adapted to be inserted.

5. In a roof flashing, the combination with a backing, of a pliablel apron secured to said backing and between which and said backing the roofing material is adapted to be inserted, and a clamp` engaging said apron to force the same into close engagement with the inserted roofing material.

6. The combination with a roof, of a wall projecting above the roof, a flashing comprising a backing and an apron between which the edge of the roofing material is inserted, and a clamp supported.. upon the wall and depending over and engaging the dashing.

7. The combination with a roof, of a wall projecting above the roof, a flashing comprising a backing and an apron between which the edge of the roofing material is inserted, a bracket supported by the wall and projecting above said dashing, a clamp depending from said bracket and overlyin the flashlng, and means for forcing sai clamp against the flashing to grip the roofing materialbetween the backing and apron of the ashin 8. The combination with a roof, of a wall ,projecting above the roof, a flashing comrising a horizontal portion ada lnserted between adjacent rows o brick and a depending vertical portion, said flashing being composed of a stiff backing and a pliable apron between which the edge of the rooting material is inserted, a plurality of ted to be horizontal brackets secured to the horizontal portion of the iashing, clamps depending from said brackets 'and overlying the vertical portion of the fiashing, and means for forcing said clamps against the flashing to tightly secure the roofing material therein.
